Problem with handshake

[Mario Guerri Maglia]

Hi,

I installed and configured a server Radius and it worked successfully 
until last week when it began to show the following message
This is the error message I got

/Thu Dec 10 15:46:14 2015 : Error: TLS Alert read:fatal:handshake failure //
//Thu Dec 10 15:46:14 2015 : Error:     TLS_accept: failed in SSLv3 read

Thanks in advance
